Definitions

  • the present invention is a caustic based, aqueous cleaning composition which is particularly suited for removing soil from the inside of soiled ovens.
  • caustic based cleaning compositions are suitable for cleaning soiled ovens.
  • U.S. patent 4,157,921 entitled “Oven Cleaning Method and Composition” discloses a thixotropic caustic composition which contains sodium, potassium or lithium hydroxide, 2 thickeners, 1 of which is a thixotropic emulsion of a copolymer of acrylic acid and ethylene, an humectant and an organic solvent. This composition is designed to be delivered from a pump spray bottle and to solidify upon contact with the soiled surface.
  • United States patent 3,829,387 discloses a caustic containing cleaning composition which comprises an alkali, a non-ionic surfactant, water and from about 3% to about 20% by weight of a solvent comprising a mixture of 2 different phenyl glycol ethers of ethylene glycol, diethylene glycol or triethylene glycol.
  • United States patent3,715,324 involves a cleaning composition containing an aqueous or substantially aqueous mixture of sodium hydroxide, a dimethyl polysiloxane, tetrasodium pyrophosphate, a polyethylene oxide mono and/or dihydrogen phosphate ester, a nonyl phenol polyethylene glycol ether and triethanolamine.
  • This highly caustic composition is designed for application to a hot surface, preferably one which is at a temperature above 93.3°C (200°F).
  • a spray cleaning composition containing caustic, a surfactant and a mixture of furfuryl alcohol and tetrahydrofurfuryl alcohol as catalyzers is described in U.S. patent 3,335,092 as being useful for cleaning preheated oven surfaces.
  • compositions involve the use of organic solvents and/or require that the oven be preheated in order to be effective cleaners.
  • the present invention is a caustic based, aqueous cleaning composition which comprises substantially on a weight/weight basis of 100% active material:
  • the caustic cleaning composition described and claimed herein is both unique and highly effective and is based on the unexpected results that it is stabilized in the 200-2,OOOx 10- 3 Pa s viscosity range without a conventicr.al thickener and is a highly effective oven cleaner which does not require the use of an organic solvent. When used to clean a soiled oven, it clings to the vertical and upper walls very satisfactorily, thus enhancing intimate contact between the cleaner and soil on all surfaces. Because it does not contain a conventional thickener such as starches, gums, or synthetic polymers, the detergent and caustic solution is readily available to penetrate and soften baked-on soil. Hence, cleaning is rapid and does not require preheating of the oven.
  • Suitable alkali metal hydroxides include sodium, potassium and lithium hydroxide with the sodium species being preferred. If desired, a mixture of these alkali metal hydroxides can be used.
  • the fatty acid hydrocarbon chain-substituted betaine can be characterized by the following structural formula: wherein y is 0 or 1, x is an integer of from 2 to 4, R 1 is a hydrocarbon chain derived from a fatty acid containing from 8 to 18 carbon atoms, R 2 ' is either CH 2 COO' or CH 2 -CHOH-CH 2 S0 3 ° and R 3 is independently H or-CH 2 0H provided that R 3 can be-CH 2 0H only when y is 0 and R28 is CH 2 COO 1.
  • the R 1 chain can be saturated as in the case of lauryl or unsaturated as in the case of oleyl.
  • fatty acid hydrocarbon chain-substituted betaines suitable for use in the present invention are dimethyl-oleyl betaine, dimethyl-cocoyl betaine wherein R 1 is derived from coconut oil (C 8 ⁇ C 18 ) and dimethyl-tallow betaine wherein R 1 is derived from tallow (C 14 ⁇ C 18 ).
  • Hydroxyethyl betaines corresponding to the foregoing formula where at least one R 3 group is -CH 2 0H have been found to be particularly effective for use in the present invention.
  • examples of hydroxyethyl betaines are those in which R 1 is derived from soybean oil, coconut oil, tallow or hydrogenated tallow.
  • Suitable fatty acid hydrocarbon chain-substituted amido betaines include dimethylcocoamido betaine, dimethyloleylamido betaine, and dimethyl-tallow amido betaine.
  • Suitable fatty acid hydrocarbon chain-substituted sulfo betaines and amido sulfo betaines include dimethylcocoyl sulfo betain, dimethyl-oleyl sulfo betaine, dimethyl-cocoyl amido propyl sulfo betaine and dimethyl-oleyl amido propyl sulfo betaine.
  • These compounds or mixtures thereof, in combination with the alpha olefin sulfonate act as synergists which promote soil removal performance. Furthermore, they are instrumental in stabilizing the viscosity of the resulting composition in the range of 200 to 2,000x 10-a Pa s at room temperature. They can be used separately or in combination one with the other.
  • the long-chain alpha olefin sulfonate is characterized in that it is obtained from the sulfonation of an n-alpha olefin of the structure: where R is an alkyl chain of 8 to 18 carbon atoms.
  • the alpha olefin sulfonate in itself, is a degreasing agent and an emulsifier of fats and oils. Its function in the formulation is to promote caustic penetration of the soil. As it turns out, in combination with the betaine, the ability of the composition to cling to the vertical surfaces of the oven is promoted.
  • the 3 components described up to this point i.e. the alkali metal hydroxide, betaine and alpha olefin sulfonate, at the recommended concentrations in water, result in a fluid of high viscosity with the appearance of a gel.
  • a fourth agent hydrotropic agent
  • the hydrotropic agent is selected for its ability, in combination with the 3 components described above, i.e.
  • the alkali metal hydroxide, betaine, and alpha olefin sulfonate to provide a viscosity within the range of 200 ⁇ 2,000x10 3 Pa s at room temperature and, preferably, to stabilize it in that range even when subjected to stressful environmental conditions such as heat 36.7°C (98°F) and cold -14.4°C (6°F).
  • the cleaning composition of this invention is particularly suitable for use with the oven cleaning device disclosed in US patent specification No. 4 475 835. When used with this device, the preferred viscosity range of the present cleaning composition is 500 to 800x10- 3 Pa s. In this range, the composition is easily applied with the device's scrubber pad and it clings to the vertical walls of the oven in sufficient quantities to perform its intended function.
  • This viscosity range is also preferred for application with a sponge.
  • the preferred viscosity would be within the range of from 200 to 500 mPa . s.
  • an increase in viscosity above 800 mPa . s results in a tacky material and greater quantities (more than is really needed) are required just to cover the soiled surface.
  • the viscosity decreases below 500 the tendency to run (flow) down the vertical walls of the oven becomes more pronounced, resulting in a waste of product.
  • a lower viscosity can be tolerated when a pump spray dispenser is used because the delivery rate per squeeze is such that the foregoing problems can be avoided unless the same area is repetitively covered with fluid.
  • Suitable hydrotropic agents include the class of phosphate ester hydrotropes such as those known in the art for their usefulness in high alkaline builder solutions. Suitable phosphate esters are commercially available under the trade names Triton H-66, Triton H-55 (Rohm & Hass Co), and Gafac BG-510, or Gafac RA-600 from GAF. Another class of hydrotropic agent which may be used is that of the tridecyl oxypoly (ethylenoxy) ethanols with a 9 to 15 mole ethylene oxide content per mole of tridecyl oxypoly ethanol.
  • the preferred class of hydrotropic agent is that of the aromatic and polyaromatic sulfonates optionally substituted with 1 or more alkyl groups.
  • the optional alkyl groups in these sulfonates may be methyl, ethyl, propyl or butyl.
  • these sulfonates can be in the form of their sodium or potassium salts with the sodium salts being preferred.
  • Suitable compounds within this class include the sodium or potassium salts of xylene sulfonate, methyl naphthalene sulfonate, cumene sulfonate or mixtures thereof.
  • the preferred species is sodium methyl naphthalene sulfonate.
  • hydrotropic agent required to provide a composition having the viscosity desired for its intended use will vary depending on the particular hydrotropic agent selected and the identity and concentration of the other ingredients in the composition. However, the amount required in any specific composition can be readily determined without undue experimentation by empirical viscosity testing using a standard Brookfield viscometer.
  • a pigment will be added to the composition to provide opacity thereby adding visibility to the product during use.
  • Any pigment which will provide the desired opacity and is not detrimentally reactive with the other ingredients is satisfactory; titanium dioxide is preferred.
  • the rutile crystalline structure is particularly preferred because of its greater opacifying power in comparison to the anatase structure.
  • a chelating agent will be added to the cleaning composition to stabilize the alkali metal hydroxide and inhibit possible flocculation arising from the presence of ions such as calcium, magnesium and iron as impurities in the water and the various raw materials.
  • Suitable chelating agents include alkali-metal salts of ethylene diamine tetraacetic acid (EDTA), nitrilo triacetic acid (NTA) and gluconic acid.
  • the preferred concentration is 1.2% to 1.8% by weight of the 100% active material.
  • a 100 kilogram batch of the cleaning composition is prepared as follows:
  • the viscosity of the product was found to be slightly over 1 Pa s at room temperature as determined by use of a standard Brookfield viscometer. This viscosity can readily be adjusted to any lower viscosity by adding small increments of methyl naphthalene sulfonate, typically in the amount of 0.025% wt/wt of the formulation, until the desired viscosity is reached.
  • the resulting composition was allowed to cool overnight and the viscosity adjusted the next day by the addition of small additional increments of the aromatic sulfonate as hydrotropic agent (methyl naphthalene sodium sulfonate in runs I-V and VIII and a modified polyalkyl polynuclear metallic sulfonate in runs VI and VII).
  • aromatic sulfonate as hydrotropic agent (methyl naphthalene sodium sulfonate in runs I-V and VIII and a modified polyalkyl polynuclear metallic sulfonate in runs VI and VII).
  • run VII 5 g of EDTA was added with the alpha olefin sulfonate.
  • Formulations I through VIII were evaluated in terms of soil removal from soiled porcelain oven tiles using a method derived from the CSMA procedure for oven cleaner evaluation *. The formulations provided good to excellent cleaning ability. The viscosity data are indicative of the stability of the product when submitted to stressing environmental conditions. The 3 cycles of freeze-thaw is particularly rigorous as the product is repetitively brought to a frozen state and subsequently thawed to room temperature.
  • a 100 kg batch of a composition corresponding to the present invention in which there was used a dihydroxyethyl betaine was prepared by the following technique.
  • step E The batch viscosity adjustment of step E is carried out by first weighing out 1000 g of the in process material into a 1,500 ml beaker batch and cooling it to 22.2 ⁇ 1.1°C (72° ⁇ 2°F). At this point (step B), the viscosity is checked with a Brookfield viscometer at 22.2 ⁇ 1.1°C (72° ⁇ 2°F). If the viscosity is greater than 0.8 Pa s, there is added 1.0 ⁇ 0.05 g of methyl naphthalene sulfonate (step C) and steps B and C are repeated (step D) until the viscosity is in the specified range (0.5 to 0.8 Pa s at 22.2°C (72°F) in this case).
  • the viscosity is rechecked with a new 1,000 g sample of the in process batch to which is added the total quantity of methyl naphthalene sulfonate added in steps C and D.
  • the amount of methyl naphthalene sulfonate to be added to the production batch is calculated as follows:
  • Table III provides the preferred formulation when a dihydroxyethyl betaine is used.
  • This invention is a novel liquid oven cleaning composition stabilized in the viscosity range of 200 to 2,000x10-3 Pa s at room temperature. It is an effective and quick acting liquid cleaner with a high caustic content that clings to the oven walls without the need for conventional thickeners. As a result, it is easily and efficiently applied with a sponge, a scrubber or a pump spray, avoiding the messiness inherent in the brush application of viscous gels. Because of the relatively low viscosity and the special surfactant blend, the material can penetrate soils effectively and achieve a better soil contact than gels or foams.
  • composition is extremely effective and need contain only alkali, surfactants, a hydrotropic agent (optionally a pigment and/or a chelating agent) and water.
  • An organic solvent is not required, and in the absence of such solvents the composition does not generate irritating organic fumes or vapors while in use.
